Communication with Net went very well and Check in was super smooth! Location is great! Right at the BTS Ekkamai and opposite of Gateway, which has a lot of restaurants, food stalls, shops and 24h super market.
The room was big enough for 2, max 3. Apartment was like on the pictures and quite clean.
Only downside was the Air conditioner, it didn't cool down the room enough, so we couldn't sleep well.
Also we met a few little cockroaches in the kitchen, which is actually quite normal in Bkk but still yucky. I informed Net about it, so I hope it'll be better.
